'VENTILATING DEVICE.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed August 9. 1907. Serial No. 387.772.

To all whom it may concern:

.Be it known that I, LESLIE S. HACKNEY, of St. Paul, Ramsey county,Minnesota, have invented certain new and useful Improvements inVentilating Devices, of which the following is a specification.

My inventionrelates to a ventilating apparatus and the object of theinvention is to .provide means capable of quick and'easy attachment to awindow for the purpose of supplying fresh air to the room and removingthe foul air therefrom.

A further object is to provide an appara tus, that is particularlyadapted for sick rooms and movable from one room to another when used ina hospital to supply fresh air to the patient and remove the impure airaround the bed. v r

The invention consists generally in various constructions andcombinations, all as hereinventionto a window, and the manner ofconducting the fresh air to the bed and removing the impure airtherefrom. Fig. 2 is a detail view. illustrating the adjustable featureof the board on which the apparatus is mounted, to adapt it for windowsof different width. Fig. 3 is a detail view illustrating the outside ofthe board. Fig. 4 is a sectronal view illustrating the intake and outletpipes permanently inserted in the outer wall of the building. Fig. 5 isa detail sectional v ew lllustrating the position of the intake pipesand a cap for closing the same.

n the drawing, 2 represents the wall of the room, 3 the window sash, 4.a shelf adapted to rest on the sill 5, and 6 a plate adapted-to fitbetween the sill and the sash and having a movable extension 7 at oneend adjustably connected with the part 6 through a slot '8 and thumbscrew 9 to allow the board to be fitted into windows of differentwidths. 10 is a suction fan having a pipe 11 extending through the board6 and upwardly therefrom to a oint near the bottom of the upper sash andaving an open outer end through which I the impure air drawn from theroom by the operation ofthe fan is discharged.

A tube 12 is connected to the fan 10 and has a funnel 13 at its oppositeend which, as shown in Fig. 1, depends to a point near the floor, asuflicient suction being created by the revolution of the fan towithdraw all the foul or impure air which collects in the lower part ofthe room. The tube 12 may be made of any suitable length to permit thefunnel to be placed in any part of the'room or under or in the bed ifdesired.

I prefer to provide a fresh air tube 14 having a funnel 15 at its innerend and fitting, within an opening 16 in the extension 7, over which agauze screen 17 is placed. This tube 14 may be hung over the head of thebed where the fresh air can be delivered to the patient and wheneverdesired the tube and funnel can be moved to other points in or on thebed or to other parts of the room.

The funnel may be held in the hand and the fresh air inhaled.

, It is extremely diflicult to ventilate a sick a window where the draftwill blow directly upon the sick person. It has also been found verydifficult to properly ventilate bed clothing without danger of exposingthe patient to cold or drafts. With this apparatus it will beunnecessary to move the erson in the bed, the fresh air tube being paced in any desired position in the room or on the bed and the impureair funnel being adjusted wherever it is desired to create thecirculation and change the air.v In hot weather this apparatus will befound very useful as the circulation can, be maintained through the bedand the impure air entirely removed from the room.

I prefer to employ an electric motor 18 for driving the fan, alsomounted on the board 6 and capable of movement therewith from place toplace and adapted to be driven by the electric'light current which maybe delivered thereto through the conductor 19 that is plugged into thelight 20 in the usual way.

Instead of having the intake and exhaust tubes mounted in a board thatis capable of adjustment in a window, these tubes may be connected withfresh air and foul air pipes permanently arranged in the building wall.The operation of the apparatus, .however, would be substantially thesame. The use of the board renders the device capable of and outletpipes that are permanently 31-.

ranged in the wall of the building. 21 represents the intake pipearranged in the building wall above the'window and having an inner-endon which the tube 14 is adapted to be fitted. A removable cap 22-isprovided for closing the inner end of the pipe when the device is not inuse.

For taking out the foul air I prefer to provide a flue 23 mounted on theoutside of the wall 'of the building and extending up to a point nearthe roof. The lower end of the ipe 23 is extended inwardly through. thebase board and the foul air tube may be fitted over this inner end, orin some instances the tube may be omitted and the foul air allowed topass directly into the open end of the flue. Considerable suction willbe created in the flue 23 and the foul air accumulating in the lowerpart of the room will pass off therethroug I have shown this ventilatingdevice in connection with a bedroom but do'not wish to confine 'myselfto such use as his well adapted for ventilating purposes in living andother rooms of residences, hotels, or other buildings and in thecompartments. or staterooms of cars and steamshipa.

I claim as my invention:

1. A ventilatin a paratus comprising a board adapted toe tted into awindow between the lower sash and sill, a suction fan having a pipeextending through said board to the open air, said fan being attached tosaid board and movable therewith from place to place, an .electric motoralso attached to said board and connected with-said fan, a flexible tubeconnected with said fan and having a funnel at its free end adapted tobe inserted in or under a bed, and a second flexible tube extendingthrough said board to the open air and having a discharge'funnel at itsfree end, substantially as described.

2. The combination, with a board, having an adjustable extension toadapt it for windows of different width, and capable of fitting betweenthe lower sash of the window and the sill, a suction fan having a pipeextending through said board to the open air, a flexible place, and afresh air tube connected with'an' opening in said board and having afunnel at its free end and through which fresh air is delivered into theroom, substantially as described.

3. The combination, with a board comosed of adjustable sections andadapted to be fitted to windows of different Width between the lowersash and the sill, an impure air pipe extending through said boardandupwardly to a point near the top of the sash,

a flexible tube connected with said pipe, and V a second flexible tubeextending lnto an opening in said board and communicating therethroughwith the outside air, substantially as described.

' 4. A ventilating apparatus comprising pipes arranged to extend throughan outer wall and having open outer ends communicating with theatmosphere and tubes adapted to be fitted on the inner ends of saidpipes and having funnels, one of said tubes serving as a fresh air inletand the other tube as an exhaust for the foul air, substantially asdescribed. l

5. A ventilating apparatus comprising pipes arranged to extend throughan outer ,wall and having open outer ends commun1- eating with theatmosphere and tubes adaptedto be connected to the inner'ends of sa dpipes, one of said tubes serving as a fresh all in foul air, both ofsaid tubes having their inner ends exposed to the atmosphere and capableof being moved from place to place, where the ventilation of the spacemay be regulfi substantially as descrlbed.

In witness whereof, I have-hereunto set my hand this 29th day of July, 10
